4. Diagnostics
Three diagnostics modes are available via connector 4 (Figure 1). The connector has two
inputs. If either or both inputs are Low then diagnostics mode can be activated. When both
inputs are High – not connected - (inactive) the SR5 is in normal run mode.
To enter diagnostics mode, set the jumpers to perform the required test, set the rotary switch to
position 0, then press the program button 3 (Figure 1) until the LED flashes Yellow.
Note: If the LED stays Green then Diagnostics is not available.
4.1 Inhibit / Accept line and Inductive Noise Test
This mode is used for checking inhibit and accept lines in a loop-back test. Only the status
of inhibit lines 1 to 6 are used.
The inhibit line must be Low to activate the corresponding accept line.

The SR5 will also ‘clap’ the accept gate a number of times, depending on the level of noise
present on the sensors. The more ‘claps’, the more noise.
¾ 0 claps No detectable noise.
¾ 1 to 5 claps Small amount of noise – acceptable.
¾ > 5 claps Unacceptable amount of noise.
This only happens when the diagnostics mode is first entered. In order to repeat, press the
program button, the LED will turn green. Press the program button again until the LED
flashes yellow.
To exit the diagnostic tests, remove the links and press the program button until the LED
turns Green.
